The value of debridement and Vacuum-Assisted Closure (V.A.C.) Therapy in diabetic foot ulcers

DIABETES/METABOLISM: RESEARCH AND REVIEWS, Issue S1 2008
Magnus Eneroth
Abstract Background Treatment of diabetic foot ulcers includes a number of different regimes such as glycaemic control, re-vascularization, surgical, local wound treatment, offloading and other non-surgical treatments. Although considered the standard of care, the scientific evidence behind the various debridements used is scarce. This presentation will focus on debridement and V.A.C. Therapy, two treatments widely used in patients with diabetes and foot ulcers. Methods A review of existing literature on these treatments in diabetic foot ulcers, with focus on description of the various types of debridements used, the principles behind negative pressure wound therapy (NPWT) using the V.A.C. Therapy system and level of evidence. Results Five randomized controlled trials (RCT) of debridement were identified; three assessed the effectiveness of a hydrogel as a debridement method, one evaluated surgical debridement and one evaluated larval therapy. Pooling the three hydrogel RCTs suggested that hydrogels are significantly more effective than gauze or standard care in healing diabetic foot ulcers. Surgical debridement and larval therapy showed no significant benefit. Other debridement methods such as enzyme preparations or polysaccharide beads have not been evaluated in RCTs of people with diabetes. More than 300 articles have been published on negative pressure wound therapy, including several small RCTs and a larger multi-centre RCT of diabetic foot ulcers. Negative pressure wound therapy seems to be a safe and effective treatment for complex diabetic foot wounds, and could lead to a higher proportion of healed wounds, faster healing rates, and potentially fewer re-amputations than standard care. Conclusions Although debridement of the ulcer is considered a prerequisite for healing of diabetic foot ulcers, the grade of evidence is quite low. This may be due to a lack of studies rather than lack of effect. Negative pressure wound therapy seems to be safe and effective in the treatment of some diabetic foot ulcers, although there is still only one well-performed trial that evaluates the effect.

A Clinical Review of Infected Wound Treatment with Vacuum Assisted Closure® (V.A.C.®) Therapy: Experience and Case Series

INTERNATIONAL WOUND JOURNAL, Issue 2009
Allen Gabriel
ABSTRACT Over the last decade Vacuum Assisted Closure® (KCI Licensing, Inc., San Antonio, TX) has been established as an effective wound care modality for managing complex acute and chronic wounds. The therapy has been widely adopted by many institutions to treat a variety of wound types. Increasingly, the therapy is being used to manage infected and critically colonized, difficult-to-treat wounds. This growing interest coupled with practitioner uncertainty in using the therapy in the presence of infection prompted the convening of an interprofessional expert advisory panel to determine appropriate use of the different modalities of negative pressure wound therapy (NPWT) as delivered by V.A.C.® Therapy and V.A.C. Instill® with either GranuFoamÔ or GranuFoam SilverÔ Dressings. The panel reviewed infected wound treatment methods within the context of evidence-based medicine coupled with experiential insight using V.A.C.® Therapy Systems to manage a variety of infected wounds. The primary objectives of the panel were 1) to exchange state-of-practice evidence, 2) to review and evaluate the strength of existing data, and 3) to develop practice recommendations based on published evidence and clinical experience regarding use of the V.A.C.® Therapy Systems in infected wounds. These recommendations are meant to identify which infected wounds will benefit from the most appropriate V.A.C.® Therapy System modality and provide an infected wound treatment algorithm that may lead to a better understanding of optimal treatment strategies.

V.A.C.® Therapy in the management of paediatric wounds: clinical review and experience

INTERNATIONAL WOUND JOURNAL, Issue 2009
Mona Baharestani
ABSTRACT Usage of negative pressure wound therapy (NPWT) in the management of acute and chronic wounds has grown exponentially in the past decade. Hundreds of studies have been published regarding outcomes and methods of therapy used for adult wounds. This treatment is increasingly being used to manage difficult-to-treat paediatric wounds arising from congenital defects, trauma, infection, tumour, burns, pressure ulceration and postsurgical complications in children, although relatively few studies have been aimed at this population. Given the anatomical and physiological differences between adults and children, a multidisciplinary expert advisory panel was convened to determine appropriate use of NPWT with reticulated open cell foam (NPWT/ROCF) as delivered by Vacuum Assisted Closure® (V.A.C.® Therapy, KCI Licensing, Inc., San Antonio, TX) for the treatment of paediatric wounds. The primary objectives of the expert advisory panel were to exchange state-of-practice information on paediatric wound care, review the published data regarding the use of NPWT/ROCF in paediatric wounds, evaluate the strength of the existing data and establish guidelines on best practices with NPWT/ROCF for the paediatric population. The proposed paediatrics-specific clinical practice guidelines are meant to provide practitioners an evidence base from which decisions could be made regarding the safe and efficacious selection of pressure settings, foam type, dressing change frequency and use of interposing contact layer selections. The guidelines reflect the state of knowledge on effective and appropriate wound care at the time of publication. They are the result of consensus reached by expert advisory panel members based on their individual clinical and published experiences related to the use of NPWT/ROCF in treating paediatric wounds. Best practices are described herein for novice and advanced users of NPWT/ROCF. Recommendations by the expert panel may not be appropriate for use in all circumstances. Decisions to adopt any particular recommendation must be made by the collaborating medical team, including the surgeon and wound care specialist based on available resources, individual patient circumstances and experience with the V.A.C.® Therapy System.

Comparative analysis of global gene expression profiles between diabetic rat wounds treated with vacuum-assisted closure therapy, moist wound healing or gauze under suction

Abstract How differential gene expression affects wound healing is not well understood. In this study, Zucker diabetic fatty (fa/fa) male inbred rats were used to investigate gene expression during wound healing in an impaired wound-healing model. Whole genome microarray surveys were used to gain insight into the biological pathways and healing processes in acute excisional wounds treated with vacuum-assisted closure (V.A.C.®) Therapy, moist wound healing (MWH) or gauze under suction (GUS). Global gene expression analyses after 2 days of healing indicated major differences with respect to both number of genes showing fold changes and pathway regulation between the three different wound treatments. Statistical analysis of expression profiles indicated that 5072 genes showed a >1·6-fold change with V.A.C. Therapy compared with 3601 genes with MWH and 3952 genes with GUS. Pathways and related genes associated with the early phases of wound healing diverged between treatment groups. For example, pathways involving angiogenesis, cytoskeletal regulation and inflammation were associated with elevated gene expression following V.A.C. Therapy. This study is the first to assess wound healing by whole genome interrogation in a diabetic rat model treated with different healing modalities. [source]
